According to current reports, fat transplantation is not absolutely safe. Complications such as pain, edema, congestion, hematoma and infection may occur in the early postoperative period (1 ~ 7 days), and pigmentation, excessive or insufficient transplantation volume and nodules may occur in the transplantation area within 1 ~ 3 months after operation. But the most important thing to note is that sudden blindness, shock or hemiplegia, and even death may occur during fat transplantation. The occurrence of complications will greatly affect the effect of surgery and patient satisfaction. For details, please consult the famous plastic surgery hospital in Gao Yi.
